Loco direction help please

[iomtt]

Hi   All, 

I have a life  like  N  scale E7   i  have fitted with a  Digitrax DZ 143 decoder in and after testing  it i  find  the  the  light i replaced with an LED only comes on when  the  loco is  running  in  reverse i fitted  the   led postive  leg to   blue  wire  and  the   negative leg to the  white  wire with  a  resistor  in line on the  negative side.

To  change  this  do i  need to  alter  the  wiring to  the track  pick  ups  or  alter the  CV 29  setting if s  to  what value.

You have the LED wired correctly, so your decoder CV29 needs to be changed; however, if the locomotive is running in the correct direction you have the motor leads reversed and changing CV29 will straighten out the headlight but not the motor.  If you don't want to go to the trouble of changing the motor wires, connect the headlight to the yellow wire, which is for the backup light. 

Directional headlights are not prototypical at all, so I connect both white and yellow wires to the headlight if a loco has no backup light.

Hi

Got it sorted now i  swapped over the motor wires and it works just fine now, the light working when going forwards, now all it needs is a airbrushing in U.P. colours and decalling.
